TYPE-WRITlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 605,877, dated June 21, 18981 Application filed June 12, 189'7.- Serial No. 640,577. (No model.)

To all whom it may concern:

Be it known that I, EDWARD E. HORTON, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented a certain new and useful attachment to the carriages of type-Writing machines to intimate the end of the sheet of writing material Within the machine; and I hereby declare that the following is a full, clear, and exact description of the same.

The object of this invention is to provide a type-writing machine with an attachment which will'intimate to the operator the fact that the last line on the sheet of paper within the machine has just been finished, thus obviating the necessity of continuously watching the paper to avoid writing oif the end of the paper or sheet, and to so construct the attachment that it can be easily and quickly adjusted to a sheet of paper of any predetermined length; and it consists, essentially, of the device hereinafter more fully set forth, and more particularly pointed out in the claims.

In the drawings, Figure 1 represents a perspective view of a carriage of a type-writing machine, showing the attachment applied. Fig. 2 is a detailed perspective view of the attachment and operating-pawl with the gong removed. Fig. 3 is an end elevation of the outer side of the same. Fig. 4 is a similar view from the inner side. Fig. 5 is a view of the adjustable stop. Fig. 6 is a view of the trip. Fig. 7 is a' View of the operating-pawl. Fig. 8 is a View similar to Fig. 4, but showing parts indifferent position.

' Like letters of reference refer to like parts throughout the specification and drawings.

In the drawings I have shown the attachment applied to the carriage of a Remington typewriting machine. I do not, however, intend to confine myself to the use of this attachment on anyparticular style of type-writing machine.

The general construction of the carriage of the type-writing machine is the same as that now in common use, and I do not intend specifying any of the parts other than those which are directly related to the attachment.

. A represents the platen, the trunnions B of which are journaled in the ends C C ofthe frame of the carriage. Secured to the end of the platen A adjacent to the end 0 of the frame of the carriage is a ratchet-wheel D, the teeth (1 of which are engaged by the linespacing pawl E,'pivoted to the arm f of the line-spacing lever F. That part of the linespacin'g pawl E operating the ratchet-wheel" D is similar in construction and purpose to the line-spacing pawl now used. This pawl, however, is provided with an upwardly-extending arm 6, from the side face of which extends a stud or pin G. Pivotally mounted on the stud G is a dog or pawl H, and depending from the dog or pawl H is an arm h, which abuts against the pin e, extending from the side face of the arm 6 below the stud G. The purpose of the pin c is to limit the downward movement of the dog H. Embracing the dog H is one end of a spring I, the opposite end of the spring being secured to the arm 6. The purpose of the spring I is to keep the dog H in position to engage the proper tooth of the ratchet-wheel and to return the dog to its normal or starting position when disengaged from the ratchet-wheel hereinafter mentioned.

J represents a standard connected to the end 0 of the carriage-frame by means of a clamp K. The standard J is located between the trunnion B and the front of the frame of the carriage. Extending from the middle of the outer side face of the standard J is astud- L, and loosely mounted upon the stud L is the hub M of a ratchet-wheel N. The periphery of the ratchet-wheel N is provided witha series of teeth 12, each of which represents one linespace. The number of the teeth 0% corresponds with the greatest usual number of T.

line-spaces on any single sheet of paper to be written upon. Rigidly mounted on the stud L on the outer side of the'hub M is a pin 0, and connected to the pin 0 and to the hub M is a recoil-spring P. Extending from the top of the outer side face of the-standard J is a stud Q, and pivotally mounted on the stud Q is a detent-pawl R, which engages the teeth n of the ratchet-wheel'N. Connected to the standard J and to the detent-pawl R is a spring S, which holds the detent-pawl in engagement with the teeth n of the ratchetwheel N. Pivotally mounted on the stud Q on the outer side of the detent-pawl R is the hub T of the strikerUof the gong. Extend- IOO position.

ing from the outer side face of the standard J immediately below the stud Q is a pin V. Connected to the pinVis one end of a spring NV, while the opposite end of the spring is connected to the striker U. The purpose of the spring V is to prevent the independent movement of the striker when the carriage has been turned back to examine the work. Extending from the hub T of the striker U is an arm X, which is adapted to rest against the pin V when the striker is in its normal The motion of the striker U when returning to its normal position after being operated is arrested by the arm X coming into contact with the pin V. Extending from the outer side face of the ratchet-wheel N is a pin Y, which is adapted to engage the arm X during the rotation or partial rotation of the ratchet-wheel to move the arm to lift the striker into an elevated position. Extending from the outer side face'of the standard J above the stud L is a stud Z, and pivotally mounted on the stud Z is a toothed trip a. Connected to the inner side face of the ratchetwheel N is a pin 2), which is adapted to lift the trip a into a position to engage the end of the detent-pawl B. This trip a is lifted into a position to engage the end of the detentpawl R at the commencement of the last line, and when the last line has been completed and the line-spacing lever is again operated the dog or pawl H instead of engaging a tooth of the ratchet-wheel N is brought into position to engage the toothed end of the trip a and operate the trip to raise the 'detent-pawl R out of engagement with the teeth of the ratchet-wheel N and hold it clear of the ratchet-wheel until the line-spacing lever has been permitted to return to its normal position. Then the detent pawl R has been lifted out of engagement with the teeth of the ratchet-wheel N, the ratchet-wheel is sharply reversed and returned to its starting position by the spring P.

The stud L extends beyond the inner side face of the standard J. Embracing the inner side face of the standard J is a verticallymovable plate 0, provided with a slot d, through which extends the adjacent end of the stud L. Mounted upon the stud L is a clamping-nut d, which looks the plate O in any adjusted position. Extending outwardly from the top of the plate 0 is a stop-pin c, which projects through and beyond the ratchet-wheel N. Part of the web '22 of the ratchet-wheel N is cut away to form an opening at" to allow of the free adjustment of the pin when the plate is being moved vertically. The web n is so cut as to form a series of stop-shoulders g g g to engage the pin 0 and limit the backward rotation of the ratchetwheel when returning to its starting position after being operated. When the plate a has been. set to bring the pin 0 into its lowermost position, it engages the stop g. When the plate has been set to bring the pin 0 into an intermediate position, it engages the stop g, and when the plate has been set to raise the pin a into its uppermost position it engages the stop 9.

On a sheet of foolscap there is ordinarily space for thirty-six lines of type-written matter, and as the foolscap size is thelargestsized paper commonly made use of the number of teeth cut on the ratchet-wheel is thirtysix, one tooth corresponding with each linespace. \Vhen the attachment has been set to announce the lines on a sheet of foolscap paper, the pin 0 at the commencement of the operation of the attachment rests against the stop g, and the relation of this stop g is such as to bring the first tooth of the ratchet-wheel N into engagement with the detent-pawl R.

As is well known,each type-writin g machine is provided with a line-spacing adjustment. When this adjustment has been set to cause each complete operation of the line-spacing lever to revolve theplaten-roll one line-space, the same operation of the line-spacing lever causes the dog H to move the ratchet-wheel N forward a space of one tooth, which is seized and held by the detent-pawl R. During the revolution of the ratchetavheel N the trip a, is raised by the pin 1), and on the thirtysixth operation of the line spacing lever F the trip a is brought into position to be engaged by the dog II. On the thirty-seventh operationof the line-spacing lever F the dog l-I engages the toothed end of the trip a and, lifting the trip a against the end of the detent-pawl R, lifts the detent-pawl out of engagementwith the teeth of the ratchet-wheel N, allowing the sharp return of the ratchetwheel N to its normal or starting position.

During the rotation of the ratchetwheel N 1 the pin Y engages and carries forwardly the arm X and lifts the striker U into an elevated position. The sharp return of the ratchetwheel to its normal position allows the striker U to fall forcibly on the gong A and audibly announce the completion of the page.

On letter-sized paper there is ordinarily space fortwenty-four lines of type-written matter, and the stop g is arranged in such relation to the teeth of the ratchet-wheel that when the pin 0 has been adjusted to engage the said stop the detent-pawl R will engage the twelfth tooth of the ratchet-wheel in order that twenty-four operations of the linespacing lever F will cause the pin 1) on the ratchet-wheel N to raise the trip a into a position to be engaged by the dog H on the twenty-fifth operation of the line-spacing lever and lift the detent-pawl R out of engagement with the teeth of the ratchet-wheel and allow of the sharp return of the ratchet-wheel to its normal or starting position at the twelfth tooth, permitting at the same time the fall of the striker U on the gong A, audibly announcing the completion of the page of the lettersheet.

The relation of the stop g" to theteeth n of the ratchet-wheel N is such that when the pin a has been moved into position to engage the stop g the detent-pawl R will engage the twenty-fourth tooth of the ratchet-wheel in order that on the thirteenth operation of the line-spacing lever the detent-pawl R will be raised out of engagement with the teeth of the ratchet-wheel N in the manner hereinbefore described to allow of the sharp return of the ratchet-Wheel and striker.

The dog H moves the ratchet-wheel N forward only one tooth on each complete opera tion of the line-spacing'lever, without reference to the width of line-spacing to which the line -spacing mechanism is adjusted. The wide line-spacing is usually one-half wider than the normal line-spacing and the narrow line-spacing one-half of the normal line-spacin g. It therefore follows that if the wide spac: ing isemployed in writing on a sheet of foolscap paper there will be only two-thirds the number of the normally-spaced lines and that if the narrow line-spacing is employed there will be double the number of the normallyspaced lines to the page.

In the former case the pin a will be set to engage the stop g in order that the ratchetwheel will commence its work at the twelfth tooth, and in the latter case the pin a will be set to engage the stop 9 and two complete operations of the ratchet-wheel will be required before the last line in the page has been typewritten. In this latter case the two complete operations of the ratchet-wheel N will necessitate two soundings of the gong to the page. On the first sounding the operator will observe that only one-half the page has been written upon, and on the second sounding he will observe that the page has been completed.

The dog H when it engages the trip a to lift the detent-pawl R out of engagement with the teeth of the ratchet-wheel N holds the detent-pawl R out of engagement a sufficient length of time to allow of the return of the ratchet-wheel.

I do not wish to confine myself to any particular number ofteeth on the ratchet-wheel nor to any particular number of stops, as I may vary the teeth and stops according to the nature of the work for which the machine is being employed. Neither do I wish to confine myself' to any particular means for securing the attachment to the carriage of the typewriting machine, as I may connect it either permanently or temporarily in any suitable manner. Nor do I wish to confine myself to the use of the pin 0 and stops 9 g g", as any equivalent construction will answer the purpose equally as well. Nor do I wish to confine myself to connecting the dog H to the linespacing pawl E, as I may connect it directly to the line-spacing lever F.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-
